Biomass and nutrient content of the bisley experimental watersheds, luquillo experimental forest, Puerto Rico, before and after hurricane Hugo, 1989
The biomass and nutrient content of two steepland watersheds were estimate using allometric equations and nutrient concentrations derived from a subsample of the vegetation. Prior to the passage of Hurricane Hugo en September 1989, the watersheds had a total vegetative biomass of 301 tons/ha,75 percent of which was aboveground. The total nutrient content of this vegetation was 907, 49, 644, 653, and 192 kg/ha for N,P,K, Ca,(2.13), and Mg respectively and varied with topographic setting. Concentrations per unit dry weight of P (0.16),(2.49) Ca (2.13),and Mg (0.62) in aboveground vegetation were similar to other steepland tropical forests, while the concentration of N (2.9) was greater. Following the passage of Hurricane Hugo, the standing aboveground biomass was reduced to 113 t/ha and the aboveground nutrient content of the forest was reduced 45 to 48 percent
